Viral coat proteins decrease the gene silencing activity of cognate and heterologous viral suppressors.

Plant viruses have evolved different viral suppressors of RNA silencing (VSRs) to counteract RNA silencing which is a small RNA-mediated sequence-specific RNA degradation mechanism. Previous studies have already shown that the coat protein (CP) of cucumber mosaic virus (CMV) reduced RNA silencing suppression (RSS) activity of the VSR of CMV, the 2b protein. To demonstrate the universality of this CP-VSR interference, our study included three different viruses: CMV and peanut stunt virus (PSV) from the Bromoviridae, and plum pox virus (PPV) from the Potyviridae family.

First report of saffron latent virus in from Hungary.

In early April of 2018 we sampled asymptomatic autumn flowering Crocus plants (Fig. S1.) in a private collection in Hajdú-Bihar county, Hungary.

First report of meadow saffron breaking virus on wild Colchicum autumnale from a stricly protected Natura2000 site at a Hungarian National Park.

In mid-April of 2018 light green to greenish yellow linear stripes (Fig. S1.) were observed on the foliage of meadow saffron (Colchicum autumnale) plants - which are native to Hungary - at a strictly protected Natura2000 site maintained by the Duna-Ipoly National Park (DNPI).

What Is the Prevalence of Intimate Partner Violence and Traumatic Brain Injury in Fracture Clinic Patients?

Background: Individuals in violent intimate relationships are at a high risk of sustaining both orthopaedic fractures and traumatic brain injury (TBI), and the fracture clinic may be the first place that concurrent intimate partner violence (IPV) and TBI are recognized. Both IPV and TBI can affect all aspects of fracture management, but prevalence of TBI and comorbid TBI and IPV is unknown.

Questions/purposes: (1) What are the previous-year and lifetime prevalence of IPV and TBI in women presenting to an outpatient orthopaedic fracture clinic? (2) What are the conditional probabilities of TBI in the presence of IPV and the reverse, to explore whether screening for one condition could effectively identify patients with the other? (3) Do patients with TBI, IPV, or both have worse neurobehavioral symptoms than patients without TBI and IPV?

Methods: The study was completed in the fracture clinic at a community Level 1 trauma center in Southern Ontario from July 2018 to March 2019 and included patients seen by three orthopaedic surgeons.

Peanut stunt virus movement protein is the limiting factor in Capsicum annuum infection.

Cucumber mosaic virus (CMV) is one of the most devastating plant viruses, with more than 1,200 species of host plants. The host range and economic importance of peanut stunt virus (PSV) are mostly limited to legumes, despite the similar taxonomy and genome structure with CMV. Since no data are available on the background of the limited host range of PSV, RNA 3 recombinant and reassortant viruses were generated (C12P3, P12C3, C12CP3, C12PC3, C12PΔC3) to study their infection phenotype on a common host (Nicotiana benthamiana) and on a selective host (Capsicum annuum cv.
